RECEPTACLE.

Application filed September 17, 1928. Serial No. 306,443.,

This invention relates to receptacles and pertains more particularly to paper receptacles designed for use as sputum flasks or for similar purposes. The principal object of the invention. is to provide a receptacle of this character which may be cheaply manniliaotured and readily assembled. from a single sheet of material, which has improved means for interlocking the side portions, thereby ellectively to prevent collapse or casual separation of its interconnected portions, and which is equipped. with a close fitting cover portion and a pocket adapted to receive and lirictionally retain the cover. Other objects reside in the particular construction of the sputum flask hereinafter described and delined in the appended claims the novel tea tures of which are in the nature oi improve ments upon the article described in. the patent to Sheline No. 1,274,613 dated August 6,1918.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a plan view of a blank from which the receptacle is constructed;

Fig. 2 is an end view of the completely assembled. receptacle in closed position;

Fig". 3 is a simlar view in opened position;

Fig. 1 is a plan view of the receptacle shown in Fi 2 with the top portion :lolded inwardly Fig. 5 is a section through the receptacle taken on the line 55 o'lf Fin". 2, illustrating particularly the interlocking connection between the side portions thereof;

Fig. 6 is a 'lraglnentary plan view partly in section along said line showing; aninitial stage of the folding; operation POl'l Ol'lllOll upon the blank of Fig. 1; and

Figs, 7 to 10 are similar views illustrating progressive stages in the folding operation.

The improved receptacle may be iiormed of heavy paper, cardboard or other suitable ilnperforate sheet material of appropriate stiffness, and is preferably formed from a single sheet of material stamped or otherwise cut in the shape shown in Fig. 1, and provided with scored or otherwise weakened linesseparating its various portions and furnlshing guldes upon which said portions are l'olded to produce the receptacle; 1

v The blank comprises aback portion 11, a i'ront portion 12, an intermediate bottom portion 13 and atop or cover portion 14L 5 disposed at the outer end of the back portron, said portions being arrayed inv line, contrally of the blank; similar lateral portions 15 and 16 adapted to be folded along the back portion 11, and other similar lateral portions 17 and 18 adapted to belolded along the front portion 12; side portions 19 which fold upon the ends of the bottom 13 and from the sides or ends of the assembled. receptacle; similar lateral web portions 20 and 21 connecting the portion 18 to the portion 19, respectively; substantially similar tab portions 22 preferably formed as integral extensions 01" the lateral portions 16 and 18 respectively in opposite sides of the blank; and substantially similar flap extensions comprising portions 23 and 24: preferably iltorniedon the lateral portions 15 and 1.7 1-15.- s )ectively at opposite ends oi": the blank, whereby to providea blank having substan- 7. tially symmetrical sides.

The lines of liold which form visible folded edges between the lateral portions of the assembled receptacle are indicated by the numerals 25 26 and 2?; the fold lines of the tabs 22 are denoted by the numeral 28, those 01 the flap portions 23 by the numeral 29, and those of the flap tongues 24 by the numeral 30; and the top portion 1.4 may have a pair ol" parallel told lines as shown at 31 and 2-32. The side portions 19 are preferably triangular in shape and the web portions 20 andv 20 are znilapted to fold upon the lines 33 in the manner of a bellows and the lateral portions 15, 16 and 17, 1S may fold in a similar manner on diagonal lines 8% and respectively, so that the forward portions of the receptacle may be pressed rearwardly against the slanting; edges ofthe said side portion, as indicated in Fig. 2, to provide a compact assemblage.

After the blank has been formed substantially as above described, it may be folded together and its lateral portions are preferably interlocked in the following manner, as illustrated in Figs. 6 to 10. The righthand lateral portion 15 is folded inwardly along the inside of the back portion 11 and the adjoining portion 16 is folded outwardly at line 34 against the face of the portion 15 (Fig. 6), and the left-hand portions 15 and 16 are then folded over said right-hand portion in a similar manner (Fig. 7 Atthis stage the flap extension 2324 lies against the inside of the cover 14, and the tab 22 is superposed upon the flap extension. Tab 22 is then folded rearwardly on line 28 over the upper edge of right-hand portion 16 so that it lies between the outer faces of the right-hand folded portions 15 and 16 (Fig. 8). Next the flap extension 23, 24 is folded forwardly on line 29 over the folded edge of tab 22 (Fig. 9), and finally the segment 24 of the flap extension is folded rearwardly and upwardly on line 30 behind the folded edge 34of the left-hand portions 15 and 16 (Figs.

Therespective right and lefthand lateral portions 15 and 16 are thus etfectivelyinterlocked and can not become accidentally separated or pulled apart, as would be possible if the tab 22 were not provided.

The forward lateral portions 17 and 18 are folded along the inside of the front 12 and are interlocked in substantially the same manner to complete the assemblage which, before closing, appears as shown in Figs. 3 and 4. It will be noted from these illustrations that the folding and interlocking operations just described furnish a: pocket 36 between the front 12 and said interlocked tionally retained therewithin, to provide a substantially non spillable container. After opening the top or cover 14, the receptacle may readily be extended by virtue of the bellows web or end portions 2 and 21 which I .are not interlocked.
